USE OF THE FREEZING SOIL HEAVE STRESS SYSTEM TO EVALUATE THE FROST SUSCEPTIBILITY OF SOILS

The M.I.T. Freezing Soil Heave Stress System has been developed to evaluate the frost susceptibility of soils. Measurements of heave stress generation with time are made in constant volume, open system test. From a plot of heave stress versus logarithm of time an evaluation of relative frost susceptibility can be made. Data are presented from tests in the prototype equipment used for development and the Freezing Soil Heave Stress system itself which were run for the purpose of standardizing test equipment and procedures. Tests using the prototype equipment indicate the effects of variation of compaction of water content, elimination of the overnight equilibration period and scalping of material larger than the #4 sieve. Tests using Freezing Soil Heave Stress System were used to study the effects of testing temperatures which were shown to strongly influence the test results. A recommendation is made for a thermal regime to be used in subsequent testing. This recommendation and classification scheme are only tentative and final standardization will depend upon the development of a correlation between the test results and field performance. /FHWA/
